I've also had cataracts surgery, when I was a toddler. And I've always noticed that UV has bothered me and not other people, but I've never thought about if I "see" UV, or at least see it in a way that others can't. Sometimes it's enough to cause my eyes to spasm. (In fact, my aversion is so strong, while reading this summary my mind _imagined_ seeing UV light, and my eyes spasmed for a few seconds in reaction.) Anyway, now I'm wondering if anyone else has this sort of reaction.
